Active clinical trials for "Poliomyelitis"

Observational program, double-blind, placebo-controlled to study the preventive efficacy of the BiVac polio (Oral polio vaccine, divalent, live attenuated of types 1 and 3 vaccine against the incidence of acute respiratory infections, including COVID-19

Following licensing of PoliorixTM in Korea, this study will collect safety data about the routine use of this vaccine in 600 children according to the regulations of Korean Food and Drugs Administration (KFDA).

Pre-licensure studies of GSK Biologicals' PEDIARIX vaccine have shown it to be generally safe and unlikely to result in vaccine-associated serious adverse events. This post-licensure study is designed to evaluate relatively uncommon/rare outcomes in a large population cohort.

Trail To Evaluate the Immunity Duration of healthy children who already took part in " The safety and immunogenicity by different sequential schedules of bOPV and bOPV in dragee candy with sIPV, a randomized, double blind, single center and parallel phase Ⅲ clinic trial was performed in Infants of two-month old in Guangxi Province, China" and continue to search for the effects of booster immunization.

The purpose of the study is to evaluate immunogenicity and safety of three different doses of candidate hexvalent vaccine in comparison to co-administration of EupentaTM Inj. and Imovax® Polio in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine

This is an open and observational follow-up clinical trial based on the previous Phase III clinical trial of Sabin Inactivated Poliovirus Vaccine manufactured by Sinovac Biotech Co. , the purpose of this study is to evaluate the immunity persistence of sIPV in infants after 4 doses of vaccination.

In 2017, China CDC conducted a study titled "A Study of Immunogenicity and Seroconversion With Sabin IPV Schedules in China". At present, all the infants in the monitoring cohort were over 18 months old and at least one year had elapsed since the last dose of sIPV inoculation.Since there is no any data about the protection duration of two-dose Sabin IPV schedules, China CDC propose to follow up the study cohort to evaluate the proportion of seroprotection of antibody and measure neutralizing antibody titers against poliovirus at over 18 months of age infants after a 2-dose or a 3-dose primary schedule of Sabin IPV in Chinese children.

The trial is a phase III, non-inferiority, observer-blind, randomised, controlled, multicentre clinical trial with 2 parallel groups: IPV-Al SSI (investigational vaccine) and IPV SSI (reference vaccine)

Polio is a highly infectious disease caused by a virus. It invades the nervous system, and can cause total paralysis in a matter of hours. The virus enters the body through the mouth and multiplies in the intestine. Initial symptoms are fever, fatigue, headache, vomiting, stiffness in the neck and pain in the limbs. One in 200 infections leads to irreversible paralysis (usually in the legs). Among those paralysed, 5% to 10% die when their breathing muscles become immobilized. There is no cure for polio, it can only be prevented. Polio vaccine, given multiple times, can protect a child for life. Compare in newborns the immunogenicity and safety of the vaccine OPV produced by Birmex compared with the vaccine OPV produced by Sanofi Pasteur, both produced in Vero cells.

Polio or poliomyelitis is the disease caused by the poliovirus. The virus attacks cells in the spinal cord and causes symptoms of fever, sore throat, headache, vomiting, and stiffness of the neck. Patients with polio can have long-term weakness of muscles as a result of the damaged cells in the spinal cord. Occasionally, patients that recover from the disease can experience a relapse of muscle weakness. This can occur as long as 25-35 years after first having polio. The condition is called "post-polio syndrome". Not all nerve cells in the spinal cord are damaged by the poliovirus. Some nerve cells remain healthy and take over the work of the damaged cells. Researchers believe that the "post-polio syndrome" may be caused by failure of these overworked nerve cells. However, what causes these overworked nerve cells to disintegrate is unknown. The purpose of this study is to apply specific scientific tests to answer important questions about the causes and development of the post-polio syndrome. Researchers will investigate possible genetic, immunologic, and physiologic causes of the "post-polio syndrome". The study itself will not provide therapy for patients with the condition, but may lead to the development of therapies in the future.
